CURRENT DRAW
The next step is to verify the current draw. You
would only be able to know this by reading the
manufacturer’s instructions for the effects pedal
you are using. If the requirement is over 100mA and
300mA or under, you will need to use the 9V
300mA outputs on the PHOENIX. For anything less
than 100mA, you can use the 9V 100mA channels
(Note: using the high current output 9V 300mA
channels for a low current draw pedal will work fine
and will not hurt the pedal. The high output only
refers to the capacity of the current that can be
drawn). Most analog pedals (not all analog pedals),
require under 25mA, for example, most overdrives,
fuzz pedals, boost pedals, distortion and compres-
sion pedals are transistor based and do not have
the large number of components that digital pedals
do. Digital pedals have DSP chips (digital signal
processors) which are micro controllers that contain
thousands of little transistors on the single chip
along with Analog to Digital Converters (ADACs),
Memory chips and other components that draw far
greater current than analog pedals.
WHAT TO DO IF REPAIR IS NEEDED:
If the product has become defective during the
duration of the 5 year warranty, please contact
Walrus Audio and setup an RMA (Return Merchan-
dise Authorization). Once determined by Walrus
Audio that the product needs repair, Walrus Audio
will send you an RMA reference number. Then ship
the Aetos back to Walrus Audio, including your
warranty card and purchase receipt. You will also
need to include a pre-paid return shipping label in
the package. You must write the provided RMA
reference number on the box or it will not be
received. (We only accept FEDEX or UPS shipping
methods). We are not responsible for the returned
product until it is received on our dock and
scanned as ‘delivered’ by the shipping company.
Do not attempt to return a product without first
receiving an RMA reference number.
INTRODUCTION TO CLEAN (ISOLATED) POWER
The PHOENIX is designed around a two
custom-wound toroidal transformers, providing
isolation to each of the 15 regulated outputs
channels. The alternatives to multi-output isolated
power supplies are individual wall-wart and daisy
chains. Wall-warts, which do offer isolation, often
lack the filtering that is necessary for audio
applications and they take up an enormous
amount of space. The daisy chain power supplies,
while being cheap in price, often have grounding
issues as a result of having multiple pedals pulling
different currents from the power source creating
ground loops and magnetic field issues. The noise
is increasingly evident if you are powering higher
current modulation effects or more than a few
pedals. The advantages of isolated power supplies
are well documented, but in summary, having
each pedal in your chain have its own isolated
power channel prevents ‘leakage’ of ground loops
or the magnetic field of one pedal onto the power
channel of another. These ground loops are often
what introduce the hum and buzz into the signal
chain. Isolated or “Clean Power” is the best choice
for serious players and highly recommended for all
Walrus Audio products.
POLARITY
The next step is to check the polarity of the device
you are using. The vast majority of DC powered
effects pedals are negative ground, much to the
result of most early pedals being powered off of
9VDC batteries with the negative terminal of the
battery connected to ground. Carrying on with the
trend, most pedal manufacturers design ‘negative
to ground’. The majority of DC jacks are center
negative and have a 2.1mm center barrel. Most of
the market has followed the lead of boss and
Ibanez and has standardized this jack for their
pedals. For all standard effects pedals with center
negative 2.1mm barrels, you can use the
Black-to-Black barrel connectors. If you have a
question about the voltage requirement of your
pedal or which of the PHOENIX outputs to use,
contact us at sales@walrusaudio.com
WARNING:
1) Input Voltage Requirements – 230V (60Hz).
This product will be destroyed if any other input
voltage is used voiding the warranty.
2) If backplate is opened, the warranty is
immediately voided. For repairs or questions,
contact Walrus Audio directly at sales@wal-
rusaudio.com
3) Always check the power requirement of the
pedal you are plugging in to,
4) Never plug an amplifier or any other device
that is rated over 200Amps into the 120V
courtesy power input.
